Pre-Christmas is very important, and it is stressful, and, you know, even in the biblical story... travelling on the donkey in a stressful environment.
It's so nerve-wracking to be on a set. They're the most stressful place in the world, because you're making something permanent, and there are so many people relying on you in a lot of ways.
Novels are so much unrulier and more stressful to write. A short story can last two pages and then it's over, and that's kind of a relief. I really like balancing the two.
